Man to be sentenced for wife murder in Tas

Hobart man Klaus Dieter Neubert is due to be sentenced for the murder of his estranged wife, more than two years after the daylight shooting that claimed her life.

In February a jury found the 74-year-old guilty of the May 2015 killing of Olga Neubert, 37, and on Wednesday Tasmanian Supreme Court Justice Michael Brett is scheduled to convict and sentence the German-born gunman.

The trial jury agreed with prosecutors that on the day of the shooting Neubert was in a rage, frustrated that his marriage had broken down and angered that his wife rejected a $600,000 settlement offer.

When he spotted her in traffic he used his Mercedes four-wheel drive to block her car and used a shortened rifle to fire repeatedly into the driver's window of her Peugeot hatchback, before approaching the car and resting the gun barrel against her skull to inflict the fatal shot.

Neubert is also expected to be sentenced in relation to the grievous bodily harm of a passenger in the Peugeot, Josephine Ramos Cooper, who lost two fingers in the attack.

She is suing Neubert for $2.4 million in the Supreme Court's civil division in a trial which also continues on Wednesday.
